本试验始于1980年,包括四种株行距,二个接穗品种和二个砧木品种。株行距分别设有8、15呎和15、20呎各两种;接穗品种为哈姆林和伏令夏橙,分别代表早熟和晚熟品种;砧木为迈兰粗柠檬和鲁斯克枳橙,分别代表乔化和半乔化砧。试验采用复裂区方法,四次重复,接穗品种为主小区,另设树高,行、株距和砧木等副小区,每小区为4行×6株,其中10株(中间2行×5株)用于采集试验材料。苗木于1980年2月份种植并采用常规的管理措施。现将种植后头五年里,接穗、砧木和株行距对树体生长、无机营养、果实产量和品质及冻害的影响作一总结报告。
This test began in 1980 and included four plantar spacing, two scion varieties and two rootstock varieties. Plant spacing respectively with 8,15 feet and 15,20 feet each two; scion varieties Hamlin and Vladimir summer orange, respectively, on behalf of early maturity and late maturing varieties; rootstock is Meran rough lemon and Russk orange, respectively Represented Qiao and semi-Joe anvil. The experiment used the method of repeated splitting area, repeated four times, and the scion varieties were the main area. There were 4 sub-areas of tree height, row, spacing and rootstock. Each area was 4 rows × 6 strains, of which 10 ) For the acquisition of test material. Nursery stock was planted in February 1980 and subjected to conventional management practices. Now the first five years after planting, scion, rootstock and spacing of trees on the tree growth, inorganic nutrition, fruit yield and quality and frost damage made a summary report.
